[PATCH] D115808: [DAGCombiner] Avoid combining adjacent stores at -O0 to improve debug experience

[Shivam Gupta via Phabricator via llvm-commits]

xgupta added a comment.

There is some problem with the script when I generate .ll file with -g flag and use it to generate CHECK lines it will not work, but it work when the test case has no debug info. This debuginfo test also doesn't use the script for check lines https://github.com/llvm/llvm-project/blob/main/llvm/test/CodeGen/RISCV/dwarf-eh.ll.
